Site planning timetable
The following guidelines can be used to monitor the progress of your
pre-installation preparation. The time between placing an order and actual
arrival can vary, and we recommend conferring with your HP
representative to determine the best estimated delivery dates for preparation
of your site.
The following are items that may require several weeks of lead time to
complete:
• Acquiring required power connectors
• Arranging for an electrician
• Adding or modifying air conditioning
• Building alterations
• Placing an order for data comm equipment
Due to potential delays, we recommend that the suppliers of the listed
services be contacted as soon as you have placed your order:
• Schedule the site planning visit with your HP CE to discuss questions
concerning site planning.
• Select an appropriate location for the disk array and create a plan
outlining the physical arrangement of the equipment, including related
furniture.

Preparing for installation
This chapter provides information for planning and preparing your site
before and during installation of your HP Disk Array XP128.
Before installing your HP Disk Array XP128, your site data center
computer room must meet the requirements described in this chapter.

Safety requirements
The following sections contain information to help you properly prepare
your facility for the arrival of your disk array.
Site safety consideration
When making decisions concerning site safety, your first concern should be
the safety of your personnel and then the safety of your equipment. Two
major safety considerations for any computer site are fire safety and
emergency power-off. If you have any questions about site safety, consult
your HP CE, your insurance carrier, and local building inspectors for safety
recommendations.
Fire safety
When considering fire safety, consult your insurance carrier and fire
department for suggestions and recommendations. They can analyze your
existing fire control systems, and advise you of any changes that may be
needed. If you are building a new site, or modifying an old site, consult
your local building codes for fire prevention and protection guidelines. You
can also consult with your local HP CE and local fire inspectors for
additional information.
Equipment servicing hazards
You, your HP CEs and HP ASEs require safe access to the disk array.
Along with the specifications listed in “General computer room
requirements” (page 21), ensure that electrical or data communication
cables do not create a safety hazard.
